Swiss Mushroom Burger
Seasoned Mushrooms | Swiss Cheese | Mayo
There’s a reason the Swiss Mushroom Burger is a fan favorite among Runzatics®. It’s probably the Swiss cheese melted over the 100% fresh hamburger patty. Or the seasoned-to-perfection mushrooms. Or the creamy mayo. Or the fact that “Swiss” is just a fun word to say. OK, correction, there are many reasons the Swiss Mushroom Burger is a fan favorite.
